What are the advantages and disadvantages of using a multi-module architecture in software systems?

Modular architecture in software systems, especially in Android, involves dividing the application into several independent modules, each responsible for its part of the functionality.

Advantages:

• Improved scalability and maintainability. Modules can be developed, tested, and updated independently.
• Code reuse. Common components can be extracted into separate modules and used across the application.
• Reduced build time. When changing one module, the entire project doesn't need to be rebuilt.
• Clear code organization. Easier to navigate, especially in team environments.

Disadvantages:

• Complex setup. Proper dependency management between modules is required.
• Increased project complexity. For small projects, modular architecture might be overkill.
• Potential versioning and compatibility issues.

Overall, modular architecture is suitable for large projects with multiple teams, where modularity and scalability are priorities.
